FULL DRAG STALL

 

@ Stall onset, recover :

Go-around thrust, lower nose to 5°

@ Go-around thrust, pull up to stick shaker until original altitude

Level off and accelerate

@ Vref , Flaps 15

@ +ive climb, Gear up, speed 210

@ 150 kts, Flaps 5

@ 180 kts, Flaps 1

@ 190 kts, Flaps up

@ 210 kts, MCT, speed 250

@ 250 kts, Level Change, speed 250

Eg           @ FL290, 50T present wind = -20 kts. Breakeven wind @ FL 330 = {–20 + (1-12)} = -31kts.

If HWC is stronger than 31 kts @ FL330, remain @ FL290.
